Anonymous is predictably peeved off, vowing to attack the firm - sometimes known as EFlicker – for its "arrogance and ignorance."

Launching the new campaign in characteristic fashion with a YouTube video (below), Anonymous pledged to "take down any business [EFlicker] have going on the Internet."

"The 99 per cent will not stop until the registration has been revoked and a public apology has been made," the masked figure representing the hacking movement said.

"Anonymous will not be the whore of the world," the mystery person added.

Early Flicker also trademarked one of the controversial collective's catchphrases – "We do not Forgive. We do not Forget. Expect us." – and is thought to be using both the logo and the saying on its merchandising.

The offending clothing co-habits the EFlicker site with other recognisable brand-related items, according to the BBC.

Neither Early Flicker nor the INPI has responded to the broadcaster's request for comment at this stage.

Anonymous typically co-ordinate Distributed Denial of Service (DDoS) attacks to make target website's unusable, with the hacking group recently knocking 10 Australian government websites offline in protest at proposed changes to the Oceanic country's Internet privacy laws.
